Isekai manga or anime is the ultimate come true fantasies of our mind’s, everyone enjoys isekai genre where you can’t expect what will come next, completely unpredictable. The first time when I read isekai genred manga I actually didn’t knew what isekai was, though I was new then in the world of manga, I liked the genre so specifically searched and read more.
The things I roughly outlined from them are basically more or less common in all of them, but I don’t say that goes for every isekai genre manga or anime.
Isekai itself means that getting summoned to different world or being transported or getting trapped into another world. This happens with the main character who is needed in that world or may be accidentally transported there. Some time’s the person dies in his origin world and get incarnated in another world with his previous memories, I personally like those where the main character is reincarnated with his memory intact from the previous life.
The first thing the main character realize that he is strong, not just strong but hell of a strong, strongest of them all in that world. Another word to describe the Main character is that he may be the smartest since he possesses the knowledge from his original world which allows him to analyze things in best way possible. He may possess a weapon or tool which make him/her invincible.
Harem is a typical fantasy of male audience, thus the main character somehow ends up with bunch of hot chicks, they may be his companions or slaves, in case of slaves they themselves surrender them to the main character after he ends up saving them from slavery, sounds like hypocritical after saving them from slavery then taking them in as slave. But not in all cases there are slaves. If the main character is an adventurer he gets surrounded by other female adventurers.
Magic is a must for an awesome story which serves as base for MC’s. He may inherit it from his parents when he is incarnated or learn it when get summoned or transferred. Eventually he is fated to be the strongest of them all.
Isekai is an awesome genre, a person suddenly finding himself in new world. They give you an all new experience even though they are fantasies like self satisfaction. Don’t watch it only for above points but to enjoy it. My personal favorite is ‘Kenja no Mago’ and many more, only thing it don” have is harem.
Thanks for reading.
